摘要

本文研究了三节点中继信道的编码策略。我们首先回顾了Cover和El Gamal对中继信道的基本编码策略。在此基础上,提出了合作与促进相结合的两种编码策略。其中一种编码策略包括Cover和El Gamal的广义策略。对于高斯中继信道的某些参数,这两种策略的可达率都高于一般化的Cover策略和El Gamal策略

New coding strategies for the relay channel
This paper studies coding strategies for a three-node relay channel. We first review the basic coding strategies of Cover and El Gamal for the relay channel. Next, two new coding strategies superimposing cooperation and facilitation are developed. One of the coding strategies is shown to include the generalized strategy of Cover and El Gamal. For certain parameters of the Gaussian relay channel, the two new strategies give higher achievable rates than the generalized strategy of Cover and El Gamal
